  1. WeatherWizard over on the WBZ blog is suggesting that soon to be “Irene” will track toward the Gulf of Mexico instead making landfall near the Alabama coast due to a stronger than expected high pressure ridge.

    Any thoughts on this scenario?

  2. Strong storm cell moving through Pembroke right now. Loud thunder. The sun came out
    briefly about an hour ago, I guess that was the fuel it needed.

    1. We watched it go by Humarock and could see the rain across the river and hear the thunder but was minimal here

  3. Speaking of thunderstorms tomorrow is a day to watch those skies. Storm Prediction Center has western and central parts of SNE in the slight risk for severe weather. The big threats look to be heavy wind, strong winds, hail, and vivid lightning.
    Thunderstorm Index at a 2 since there is the threat for some severe weather but this will be watched carefully to see if an upgrade will be needed.

  4. Amazing cumulus cloud day on the south shore. Down here, in my opinion, best day of cumulus cloud development of the whole summer. Extremely tall clouds with the tops being blown off. One storm went south of us maybe near Plymouth and a second developed west of Marshfield with lightning and thunder and then redeveloped to our north…looking like it went over Scituate or Hull.

    1. Hi Tom- It looks like It may strike again here. Started to get brighter with drizzle, and now getting darker with thunder again.

      1. Ok – I am jealous! 🙂 We’ve got some picturesque skies around MetroWest right now. Vicki – enjoy your vacation. Looks like tomorrow might be interesting for most everyone.

  5. Vicki,

    Have a great vacation and welcome back to the coast…..The cumulus cloud development seems to have calmed down the last 30 to 45 minutes. It was fun and a little bit nerve wracking being on the beach earlier watching when the sky was filled with them.

    Got a peak at the 12z EURO out the next several days and on around Friday August 26th, it projects a tropical system to be on the east coast of Florida………Looks like it has high pressure just to New England’s west, followed by a trof in the central Plains. Very interesting if that panned out, how those features would progress in time and affect one another.

    1. Funny SST- sun filled sky and feeling quite humid here now. It’s funny how the weather changes so fast. Just a thought I believe it was last labor day weekend that we were watching a storm move up the coast, not sure but I think it was Gus or Earl.

      1. Hi John.

        It was Earl and it was around the Labor Day Weekend. What I also remember was that we had a four or five day heat wave with temps in the mid 90s and I was thankful that my classroom had an Air Conditioner that made things reasonable.

      2. John you are right about Earl. Tom
        Helped us figure out the track etc. The house we rent has ocean on one side and river on the other. It’s been washed into the river two times so we went home a day early

        Tom we shifted from ocean side to river side all afternoon since the breeze kept switching and the no seums were out. It’s lovely now

        1. Hi Vicki,

          Those no seums are tough. I was up at the Avon Street Beach (right after Green Harbor in Marshfield) yesterday and tried to sit in the shade of the seawall. While I got relief from the sun, I got attacked by the no seums. For something so small, they sure are vicious. Glad to hear things are good now.

        2. Vicki- Seeing your email somehow reminded me of when
          the river house was there. A good friend of mine built alot of homes in Humarock and he still does a ton of work in that area. I hope you and your husband can grab a meal over at the bridgeway and listen to some bands.

          1. Bridgeway is very good and I dont know the name of the place, but I’ve always liked the breakfest place just over the bridge that has a small convenience store attached to it.

          2. Vicki- I know you have said your husband likes to golf. If he has a chance he should hit the Pembroke country club. A former NHL player bought the club and has dropped some money on the coarse, he was the right person to by the club as he has ties to this area. He grew up in Marshfield, but skated and golfed in Pembroke. You have been coming down here for awhile, so I am sure he must have golfed there. Sorry for the long post. I am enjoying some me time with my wife, son and his cousins all of at the fair.

        3. We love the bridgeway since polcaris bought it. I hadn’t thought of music. Well try to get there. My kids just said if we want to babysit they will too. I remember the river house. I’ve been coming here since I was one. My grandkids are fourth generation. I think it’s called sands end now Tom but was Clarks general store. I remember mrs Clark. Her son Danny has a RE company here and remembers my parents well. John my husband and son said thank you for the golf recommendation. Theyll both play 3-4 times and will try pembroke.

          1. John and Vicki,

            Maybe this is an opportunity to meet for a quick hello. I have one more week off before school starts, but I’d be happy to gather in the Humarock area some evening next week for an ice cream or something. If so, hope you wouldnt mind a couple kids tagging along. 🙂

  6. There is now a Tropical Storm Irene.
    The 18z run of the GFS brought Mass a solid 3-5″ rain storm…Not sure I’m going to buy that quite yet.

  7. “WeatherWizard” over on the WBZ blog now believes Irene taking a more northward track hitting south Florida near Miami then the Carolinas and up the coast towards SNE. WW seems to have a good understand of meteorology. It would be nice if he would post his thoughts over here as well….and speaking of WBZ, the trolls are back this evening. One giving WW a hard time and another giving it to Joe.

    There are a few others in addition to WW who post good thoughts and are civil…I wish they would post over here as well. 🙂

    1. I agree Philip weatherwizard would be good here. I would have liked to see BM come on board. I believe BM was invited awhile back. I guess he was just not interested. If that storm does make a threat at us It would be two years in a row that we have an end of summer storm to contend with. I remember with earl last year putting everything away, but that one did not effect us.

  8. Philip, I agree with your thoughts on WW completely.

    I wonder if we’re going to see explosive development on Irene. Now that it has a low level circulation, the outflow on the storm looks excellent and its over warm water. The last pressure was 1006mb……I wonder if within 8 to 12 hrs, we may see a pressure down in the low 990s or high 980s and a corresponding rampup of the winds.

  9. I would like to see weatherwizard on this blog. Baileyman would be a good addition but he only seems to blog in the winter and RMB is good as well.
    No change to the thunderstorm index from earlier which remains at a 2 since there is the threat of some severe weather but I am not sold on a widespread outbreak at this time. The biggest threat for the severe weather tomorrow looks to be in and around the NYC area to Philadelphia and there is mention of isolated tornadoes from the local NWS office out of NY. I don’t see that as a threat for us here but with that said the storms that do turn severe have the POTENTIAL for heavy rain, vivid lightning, and strong winds.

  10. Tom- It might be hard for me to meet next week, I am working very long days lately and have some things going on next week. If things change I would be up for It. I have not been to Humarock in awhile. I do head over to Scituate at times. We have friends who live in the sandhills section and have a home right on the water.

    1. Hi John.

      No problem, once the school year starts, we usually are fairly local. We can shoot for another time or at one of the general gatherings that probably will be planned down the road.

      1. Tom If I can get free I will shoot you an email. Today would have
        been perfect. I have been home all day by myself, my wife and son just returned back home.

      2. Sorry I just saw your suggestion to meet Tom. I was trying to think of a time but between friends and family here I am not sure I could break away. I am sorry we or I hadn’t thought of it earlier. It would have been fun to set a day aside to have everyone here.

  11. I was watching Frank Strait over on AccuWeather this evening and he showed those “spaghetti” maps that showed various tracks of Irene, and for now, the most likely track eventually takes Irene fairly well south of us once she leaves the Carolina coast. It looked to me that only a couple take Irene up this way. Of course Frank mostly concentrates on the southern CONUS.

  12. Irene is forecasted to become a hurricane before interacting with Hati and Cuba. If that happens it would be the 1st hurricane of the season. It is forecasted then to be a tropical storm with south Florida in the cone uncertainty. This will change so many times and a new advisory and track will be out at 11pm tonight.

    1. For now the NHC takes Irene near the south Florida coast sometime Thursday afternoon. I suspect that assuming Irene makes it this far north, it would be sometime early the following week. I would say for now, next weekend looks fine. A gazillion more model runs to go. 🙂

  13. Another nice start to a summer day…..looking forward to tracking storms later today….am amazed by how fairly consistent the models are with the projected track of tropical storm Irene.

  14. This morning’s Accuweather trivia quiz:

    What is a line thunderstorms ahead of a cold front called?

    1. They will tell you “squall line” but they are only partly right because their question is phrased incorrectly. Squall line thunderstorms do not have to occur ahead of cold fronts. But who’s nit-picking? 😉

  15. I am going to take a stab a here and go with prefrontal trough. A line of showers and thunderstorms in western parts of PA and NY at this time. I think this will weaken as it works its way to SNE. Its what’s behind that is what will have to watch for later today. A good chunk of SNE in the slight risk with the exception of the eastern parts. Will see if that changes when that is updated just before 9AM. There is even a 5% chance of a tornado far western parts of SNE and a 2% in the other parts of the slight risk area.
    Thunderstorm Index is a 3 for the far western parts of SNE and a 2 for everyone else and hopefully that 3 area will not have to be extended further east today. Will see how things play out.

  16. Good morning all. Thanks for sharing your great obs and commentary yesterday! After a short trip to Burlington Mall in the morning, I headed up to Jaffrey NH for the afternoon & evening to attend Atlas Pyrovision’s 22nd Annual Festival of Fireworks! This is a fireworks show set to a music sound track blasting over 80,000 watt speakers at Silver Ranch Air Park. This year’s show, themed on the 10th Anniversary of 9/11, paid proper tribute to the victims, families, and to all of those who serve and have served this country. Along with more somber moments, the show blew you away, 35-minutes long and 11,500 shells. Left there with ears ringing.

    Weather was excellent: Mostly sunny with a few tropical-looking cumulus around. By early evening, we could see a cluster of larger towers associated with showers/storms east of the Monadnock region. A bit later a cumulus made an attemp to blow up southwest of Mount Monadnock, then made a 2nd and successful attempt, turning into a rather short-lived 2-cell thunderstorm that quickly rained itself out and left behind an orphan anvil that then moved rapidly ESE to our south. I took several shots of the storm as it went from maturity to decay stage. As it got dark, another area of clouds tried to fire just to our NNW but failed, and the area closer to the storm then shot up a new tower but that was also very short-lived. No lightning observed. From there it was all quiet, other than the fireworks show and the crowd of thousands assembled there! Amazing. 🙂

    Working on a blog update now.
